WIRE-STRETCH ER.

SPECIFICATION forming part of Letters Patent No. 606,523, dated June 28, 1898. Application filed March 28, 1898. Serial No. 675,430. (No model.)

To all whom, it may concern:

Be it known that I, GEORGE M. DOYLE, a citizen of the United States, residing at J onesville, in the county of Lee and State of Virginia, have invented certain new and useful Improvements in WVire-Stretchers, of which the following is a specification.

My invention is an improvement in wirestretchers, and has for an object to provide a stretcher which may be operated with great power to stretch the wire from either direction, which can be quickly and securely anchored to a post, and which can be utilized in uniting the ends of wire sections, all of which will be described.

The invention consists in certain novel constructions and combinations of-parts, as will be hereinafter described, and pointed out in the claims.

Figure l is a perspective View of my stretcher as in use. i Fig. 2 is a top plan view thereof. Fig. 3 is a detail View of the stretcherbar, and Fig. 4 is a cross-sectional View on about line 4 i of Fig. 2.

My improved stretcher has a suitable frame A, which is provided with the longitudinallyextended guide B, in which slides endwise the stretcher-bar O, which has at both ends the hooks D to engage the wire to bestretched, and is provided with the rack E, which is engaged by the'segment F on the stretchinglever G, which is pivotally supported on a lateral offset H on the frame A.

The lever G may be operated to forcibly move the stretcher-bar G in either direction, so a wire may be stretched from either the right or left, as may be desired. To hold the stretching-lever and the stretching-bar with which it is meshed in any position to which they may be adjusted so the wire may be held during the manipulation thereof subsequent to the stretching operation, I provide a detent, which is preferablya pin 1, passed through an opening J in the lever and into a coincident hole J of a series formed in the frame.

At each end the frame A is provided with a hook K, such hooks being for convenience of reference designated as the holdinghooks, while the hooks on the stretcher-bar C may be described as the stretching-hooks.

such' offsets being" provided with spurs N,

which project toward each other and are adapted to bite into the post, and thus aid in the anchorage. Adjacent to the offsets M, I provide hooks O, which are preferably pivoted to the frame so they can adjust readily to the direction ,in which the chain leads thereto. The chain P is secured at one end, preferably in a link Q, to the main frame at a point midway between the offsets M, and is adapted at its other end to engage with one or the other of the hooks 0. By this construction the stretcher may be secured on either side of a post and be operated to stretch the wire from either direction.

In operation a wire can be stretched in either direction by the stretcher-bar and then laid in the holding-hook and the stretcherbar returned to stretch the Wire again, or for the purpose of bringing the ends of two wires together one can be stretched and held in the holding-hook while the other is pulled up by the stretcher-bar, when their ends can be united in any suitable manner.

Having thus described my invention, what I claim, anddesire to secure by Letters Patcut, is- I 1. A wire-stretcher comprising the frame having longitudinal guides for the stretcherbar and provided at its opposite ends with holding-hooks and having at points near said ends rearwardly-projected offsets provided with spurs extended toward each other and 5 having the hooks adjacent to said offsets, the chain secured at one end to the main frame between said offsets and arranged at its other end to engage the proper one of the hooks on the main frame,-the stretcher-bar movable lengthwise in the guides of the main frame and having at its opposite ends the stretching-hooks and between said ends the rack- -bar, and the stretching-lever meshed with said stretcher-bar substantially as set forth.

2. A wire-stretcher comprising the frame having at its opposite ends devices for engagement by a chain and the chain secured at one end to the frame between the end devices and arranged at its other end to engage said devices, and the stretcher-bar movable in the frame and its operating devices, substantially as set forth.

3. A wire-stretcher comprising the frame having a permanently-fixed holding hook or hooks and the stretcher-bar movable in said frame and havinga hook which may be moved toward and from the fixed holding-hook on the frame substantially as set forth.

4:. In a wire stretcher the combination of the stretching devices, the main frame having a rearwardly-projecting offset provided with a spur to bite into the post, the chain frame having the permanently-fixed holdinghooks at its opposite ends and a guide between said holding-hooks, the stretcher-bar operating between said holding-hooks and having the stretcher-hooks at its ends, and the lever meshed with said stretcher-bar substantially as set forth.
